Professional background

David Graham is a Consultant Gastroenterologist at University College Hospital, London. He trained at St Bartholomew’s and the Royal London Medical School and completed Gastroenterology training in North East London. He undertook a PhD at UCL focussing on the early detection of oesophageal cancer through utilisation of salivary “liquid biopsies” and artificial intelligence analysis of patient data. He has a specialist interest in Barrett’s oesophagus, oesophago-gastric cancer, endoscopic imaging technologies and interventional endoscopy. Additionally, he is part of the expert committee devising the BSG guidelines for the management of the pre-malignant and early malignant lesions of the stomach and is part of an international research collaboration aiming to improve the early detection of these lesions. Finally, David has a keen interest in endoscopy training and has helped run many live endoscopy courses at UCH.
